Here we give our Sony SRS XB23 factory reset instructions, to return this Extra Bass cylinder speaker to its default settings. Factory resetting restores the XB23 to default state. Plus, it erases any earlier paired Bluetooth devices from the speaker’s memory. Clearing memory like this stops this speaker from pairing to any nearby Bluetooth devices afterwards, until you enter new connections manually. Moreover, you might factory reset to get the unit ready for sale or re-gifting, or to stop the XB23 from pairing wirelessly with devices you no longer want it to sync with.
Sony SRS XB23 Factory Reset Instructions, Step by Step
1. Turn the Speaker ON
Press and release the Power button for a half-second or so. Find the Power button as shown in the next picture.

Find the Power button, as shown in the last picture above.
Then, the status light comes on, as shown next.

The speaker may make a ding-dong tone sound when it powers up to announce that it has paired, should it connect to a nearby device. Or it may remain totally quiet if it does not. Whether the XB23 pairs or not though, this factory reset routine works the same way, as follows.
2. Press and Hold the Pairing and Volume DOWN Buttons Together
Find these buttons as shown next. They are both on the top button panel, as we point out in the next picture.

The XB23 then enters factory reset mode.
Then after a several-seconds pause, the speaker powers OFF, and the Power lamp goes dark, as shown next. Note that on the SRS XB23, there is no power-down sound.

3. Check that your Sony SRS XB23 Speaker Did Indeed Factory Reset
Next, power on the unit again, as explained in step 1 above.
Note that after factory reset, the XB23 comes up in Bluetooth discovery mode. The Pairing Mode lamp double flashes blue to let you know this.

This pairing light signal tells you that you may then look for this speaker on a nearby BT device, and pair to it if you so desire.
4. Done with Sony SRS XB23 Factory Reset !
The factory reset is now over. So you may now sell or gift this portable speaker, or pair it again with your favorite BT streaming devices.
After a factory reset, the XB23 no longer automatically links with any Bluetooth device. Therefore, if you’re keeping the speaker and wish to restore auto pairing, you manually link the speaker with a device. Then after that, any time that both XB23 and that device have Bluetooth turned on, and they’re near to each other, pairing between them would automatically take place once more.
